Supplemental order as to public utilities.

Whenever any rate, toll, charge, or service ordered substituted
by the public utilities commission is a joint rate, toll, charge, or service,
and the public utilities which are parties to it fail to agree upon the
apportionment of such joint rate, toll, charge, or service within twenty days
after the service of such order, the commission may, after hearing, make and
issue a supplemental order fixing the apportionment of such joint rate, toll,
charge, or service between such public utilities. Such order shall take effect
of its own force as a part of the original order.
